Abstract: Composite electrospun nanofibers mats, as a nanogenerator,
were fabricated through one-step electrospinning
method. The structure of fibers is composed of
Poly(vinylidene fluoride), PVDF, as the matrix, and Zinc oxide
(ZnO) nanoparticles; the nanocomposite were produced
using electrospinning technique in order to have the benefit
of piezoelectric properties and non-brittle behavior of ZnO
and PVDF for the application in wearable electronic devices.
Characteristics of these structures were evaluated by using Xray
diffraction (XRD), Fourier Transform Infrared (FTIR),
Differential Scanning Calorimetry (DSC) and Scanning Electron
Microscopy (SEM). Impedance and the electrical conductivity
of the fabricated composites were also evaluated
by Keithley instruments. Electrical response of samples was
measured using an impedance analyzer made in Aims Lab
(http://aims.aut.ac.ir) at room temperature. Results showed
that incorporating the ZnO nanoparticles into the PVDF
nanofibers improved the piezoelectric properties of samples
compared to PVDF samples. The electrical output of
composite samples was improved as high as 1.1 V
compared with 0.351 V for the pure PVDF samples. These
results imply promising applications, as an enhancedefficiency
energy-scavenging interface, for various wearable
self-powered electrical devices and systems.
